“Certainly we put tax-payer dollars into health care for our employees, and anything that might benefit the health to make our employees more protective and healthy, we’re going to take a look at,” Betsy Price, the mayor of Fort Worth, told WFAA.

The proposed ban in Fort Worth is one of many measures employers are taking or considering in order to discourage employees from smoking. In November, The New York Times reported that, in the last two years, the number of health insurance policies that penalize employees with higher premiums for unhealthy lifestyle choices has doubled.

According to the Times, Home Depot, Safeway, and General Mills all now demand higher premiums from certain workers. Wal-Mart recently started demanding a $2,000-a-year surcharge from some of its employees who smoke.
